Why it was recalled

The user database delivered for download contained an erroneous value. Specifically the "aO" constant of the lens AMO Sensar AR40E is listed as "0.0" in the internal lens database of the IOLMaster. The correct value is -2.420. This could lead to the implantation of lens with a wrong diopter value.

This product could cause temporary or reversible health problems — stop using it.
